Fluorine-containing 3-hydroxyflavanones and isoflavones were synthesized by epoxidation of F-containing chalcones by hydrogen peroxide under basic conditions and subsequent intramolecular cyclization of the resulting epoxides using BF3·Et2O. The ratio of products depended on the presence and position of the F atom.
通过在碱性条件下用过氧化氢对含氟查耳酮进行环氧化,然后使用BF3·Et2O对所得环氧化物进行分子内环化,合成了含氟3-羟基黄烷酮和异黄酮。产物的比例取决于 F 原子的存在和位置。
